Howdy,
  I have found a bug in the overload extension for php 4.3.2.  I know it 
is labeled as Experimental, but I thought I'd report it, since it is 
causing me problems.

I get an error

Fatal error: Only variables can be passed by reference in 
/home/waboring/overload_test.php on line 16

<?php
function do_something(&$a) {
    echo $a;
}

class FooClass {
    var $_a = 1;

    function __set($name,&$value) {
        return true;
    }  
}
overload('FooClass');

$foo = new FooClass;
do_something($foo->_a);
?>


If I don't declare __set() in FooClass, then the error doesn't happen.  
Also if I don't declare the do_something() parameter as a reference, I 
don't get the error.

I haven't tried this in the php5 cvs tree yet.
